Problems solved by technology

Therefore, for the power transmission repair personnel, they do not know the number of the tower corresponding to the distance given by the regulation, and for the control personnel, they do not know the distance corresponding to the tower confirmed by the power transmission repair personnel.
Fourth, when the transmission line or tower information is changed, it is necessary to notify multiple departments for processing, which is often time-consuming and labor-intensive, and various omissions may occur, resulting in inconsistent data among various departments
The above deficiencies have laid hidden dangers for the interdisciplinary advanced dispatching and commanding. For this reason, we propose a tower information modeling method for transmission lines

Embodiment 1

[0021] The present invention proposes a tower information modeling method of a power transmission line, comprising the following steps:

[0022] S1. The transmission lines of the power system are formed by a series of towers supported overhead, and the transmission lines are connected through substations;

[0023] S2. After modeling, the transmission line corresponds to a line. The two ends of the line are called endpoints, and the intersection of multiple lines is called a node. Each node contains multiple endpoints. Generally, a node corresponds to a substation;

[0024] S3. Multiple towers on the transmission line are divided into a group of associated line segments. The model represents it as the line is divided into multiple sub-segments by a group of sub-points. Each tower corresponds to a sub-point. The distance between the tower and the tower The line between corresponds to a line segment, the sub-point has the attributes of the unit, geographic latitude and longitude,...

[0036] In the case of the same computer with the same software and hardware configuration, the traditional single modeling method and the modeling method in this paper are compared horizontally. The experimental methods and experimental data are as follows:

[0037] There are 10, 100, 1,000, and 10,000 lines in the model, and the number of towers in each line is randomly distributed with 100 as the center. 100,000 single-threaded tower query operations are performed on them, and the time-consuming unit is seconds.

Embodiment 3

[0040] In the case of the same computer with the same software and hardware configuration, the traditional single modeling method and the modeling method in this paper are compared horizontally. The experimental methods and experimental data are as follows:

[0041] There are 10, 100, 1,000, and 10,000 lines in the model, and the number of towers in each line is randomly distributed with 100 as the center. Each time a line is randomly selected, an operation of deleting towers / adding towers is performed. A single thread performs this operation 100,000 times, and the time-consuming unit is seconds.

Abstract

The invention discloses a tower information modeling method for power transmission lines. The method is characterized in that the power transmission lines are called lines, two ends of the lines are called breaking points, transformer substations are called nodes, each tower is called a sub-node, the lines among the towers are called segments, each sub-node has the attributes of the affiliated unit and geographic position, each sub-segment has the use span attribute, and a dispatching system can directly acquire the affiliated unit of a fault point and the tower corresponding to the fault point through the distance between the fault point and a transformer substation according to the use span information among the towers and timely distribute the fault point to the corresponding unit to perform processing; the construction of the power grid power transmission lines is a progressive process, and the power transmission lines and the towers need to be added, modified and deleted at any time during the construction. By the method, informatization modeling of tower information can be achieved, tower positioning speed and precision can be increased greatly, system flexibility is enhanced greatly, and power business information interaction is facilitated.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a tower information modeling method for power transmission lines. Background technique [0002] First: The number of transmission lines in the power grid is uncertain, and transmission lines will be added or removed during the development process. At the same time, for a transmission line, the number of poles and towers is uncertain, and later maintenance involves adding and removing poles and towers. The traditional representation of fixed column numbers cannot adapt to this kind of business; second: the partial maintenance of the line is actually based on Based on the pole tower, each section of the line is maintained by the unit of the pole tower where it is located. Therefore, for long-distance transmission lines, it is very important to determine the responsible unit at the first time in the event of a failure; third: the power system dispatching is separated from th...
